Lea Michele dated WHICH Glee co-star?!

Before meeting and falling in love with Cory Monteith, who sadly passes away last year, Lea Michele used to date Matthew Morrison!

Lea revealed the saucy secret in her new book, Brunette Ambition, writing: “I had worked on Broadway with Jenna Ushkowitz and Matthew Morrison before. Matt had been a friend of mine for years, and in fact we’d actually dated back in the day for a Broadway beat.”

The two have filmed Glee together for the past five years with Matthew playing teacher Will Schuester and Lea playing his student Rachel Berry.

Lea had previously denied ever dating or being involved with Matthew until now, even saying in 2010: “I’ve known Matt for years. People are going to make things up. I think it’s just because we really are so close.”

Hmm, this makes us wonder about Lea denying the entire Naya Rivera incident…
